“…Colonization of the barnacle Chthamalus bisinuatus occurred in different times for both shores. Studies at other shores of the region suggest that C. bisinuatus recruits over the whole year, but our data suggest that some irregular peaks may occur, at least in the amongshore scale (Eston et al 1986, Tanaka & Duarte 1998. Barnacle colonization was dependent on patch size, with greater densities in the 400 cm 2 patches at Barra.…”

“…Brachidontes solisianus (d'Orbigny) and B. darwinianus (d'Orbigny) are important components of intertidal communities along the Brazilian coast, forming belts dominating the midlittoral zone (Klappenbach 1965, Eston et al 1986, Petersen et al 1986). Studies on the dynamics of mussel beds are generally dominated by work on Mytilus from temperate systems, which are larger species than Brachidontes and may form multiple layers on the rocky substrate (Seed & Suchanek 1992).…”

Edge effects and succession dynamics in Brachidontes mussel beds

Succession dynamics in natural communities can be influenced both by interactions among recruiting species and by characteristics of the gaps created by disturbances such as the perimeter:area (P:A) ratio. We carried out experiments on 2 subtropical shores in SE Brazil to investigate the influence of gap size (P:A ratio and area variable) and shape (P:A ratio constant and area variable) on the succession of mussel beds dominated by Brachidontes solisianus and B. darwinianus. Small gaps harbored more herbivorous gastropods (mainly the limpet Collisella subrugosa) and were more rapidly preempted by lateral migration of the surrounding mussels than larger gaps. The larger gaps had higher densities of the barnacle Chthamalus bisinuatus and sheltered more limpets in the edges, while the core areas had more Brachidontes recruits. Gaps with different areas but constant P:A ratios had similar succession trends. Although the processes that influence gap closure in other mussel bed species are similar to the studied one, the closure rate in Brachidontes was lower, possibly due to bed structure. However, there were differences between both mussel species, with a faster response to gap formation by B. darwinianus in comparison to B. solisianus, suggesting that disturbances can influence the distribution of these species. The relative influence of edge effects on succession processes may differ among communities dominated by different organisms, and generalizations are possibly restricted to communities composed of functionally similar species.

The larger influence of sessile adults along the perimeter on small patches can facilitate the recruitment of conspecifics or competitors (Navarrette & Castilla 1990, Minchinton 1997, influencing community structure. Another consequence of the larger perimeter relative to the area is the greater influence of the surrounding community through lateral migration (Paine & Levin 1981, Keough 1984, Sousa 1984a. In this case, patches with different areas but similar edge relationships should have similar closure rates due to lateral invasion processes (Paine & Levin 1981), but this prediction has as yet not been tested. Edge effects were tested in patches with the same shape but differing areas: small gaps are rapidly closed by invasion of the surrounding species, while large gaps close as propagules colonize from the water column (Paine & Levin 1981, Sousa 1984b, Farrell 1989. However, this pattern is not always maintained, as interactions within a specific system can result in distinct species colonization rates, sometimes impairing generalizations (Kim & DeWreede 19...

A review of models of landscape change

1989

View full text Add to dashboard Cite

Models of landscape change may serve a variety of purposes, from exploring the interaction of natural processes to evaluating proposed management treatments. These models can be categorized as either whole landscape models, distributional landscape models, or spatial landscape models, depending on the amount of detail included in the models. Distributional models, while widely used, exclude spatial detail important for most landscape ecological research. Spatial models require substantial data, now more readily available, via remote sensing, and more easily manipulated, in geographical information systems. In spite of these technical advances, spatial modelling is poorly developed, largely because landscape change itself is poorly understood.To facilitate further development of landscape models I suggest (1) empirical multivariate studies of landscape change, (2) modelling of individual landscape processes, (3) explicit study of the effect of model scale on model behavior, and (4) 'scaling-up' results of studies, on smaller land areas, that have landscape relevance.

“…A more natural and conceptually satisfying approach is based on the use of socalled Markov chain models. Such models have been used by Thompson & Vertinsky (1975) for complex simulation models of birds foraging; by Usher (1979) for problems of ecological succession; and by Eston et al (1986) to study spatial interactions between 2 species. Related methods are the transition matrix approach of Woolhouse & Harmsen (1991), used to study the dynamics of an apple aphid, and the semiMarkov model of Munholland & Kalbfleisch (1991), used to describe an insect's life history.…”
